Baldor MIN1853 manual Interlock Intlk, Ground GND, Parallel Motor Connections, Motor Connector

Motor Connections The A+, A–, B+ and B– phase outputs provide power to the motor windings. These connections are shown in Figures 3-5 and 3-6. The motor windings can be connected in series or parallel as shown in Figure 3-20. For Baldor motors, refer to MN1800 for lead information.

Interlock (INTLK)

The two INTLK pins must be jumpered together at the motor connector for the drive to apply power to the motor. If the interlock wire breaks, or the connector is removed, the current to the motor is immediately stopped, the drive faults (latched) and flashes the dual function LED labeled Over Volt./INTLK. Interlock wires longer than 5 inches can create noise generated shutdowns.

Ground (GND)

GND is internally connected to the Earth pin on the Power connector. This provides a convenient terminal for grounding the motor frame and a motor cable shield.
